Nope, there's room and need for all types of computers including the formats not yet introduced. Personal choice comes down to how much screen real estate you want, around the house, on the road or at the coffee shop.
Frankly, smartphones are fine for quick squinty checks, tablets are a fine compromise between portability and large enough to read text, I take my 17" Macbook Pro on the road for motel entertainment and emails, I love my desktop, keyboard & chair with its 24" flatscreen for morning coffee, editing photos and composing posts like this with grammatical & spellicheck accuracy but best of all is lounging on the comfy couch viewing on the 55" widescreen with a bluetooth feed from the Blackberry Playbook for movies and online documentaries.
